wantonness of power

The Creature knows about the effects of unchecked power through the
account of Safie's father's persecution (2.6.1) and the De Laceys' ruination (2.6.5), and he may have gleaned something
of its underlying assumptions from William Frankenstein's instinctive
reliance on his father's ability to punish arbitrarily (see 2.8.9 and note).
Yet, it is to Victor that the Creature speaks, and, since he has used a
derivative of "wantonness" in his earlier condemnation (2.8.1 and
note), it is perhaps to that
particularized sense of irresponsibility that he reverts here.
